[AT] tractor hauler has rubbery gunk in coolant

[charlie hill]

Sounds more like Permatex gasket sealant to me.

Drain the cooling system.  Filter and save the coolant.  Flush the system.
Put the coolant back in and top it off with fresh.  See if the problem 
reoccurs.

My 2001 Malibu has issues with a gasket that allows oil into the coolant
when the seal fails. Might be the same sort of issue.
